Sahih al-Bukhari, Hadith 4764 ⓘ
Narrated Sa`id bin Jubair: I asked Ibn `Abbas about Allah's saying:-- '.. this reward is Hell Fire.' (4.93) He said, "No repentance is accepted from him (i.e. the murderer of a believer)." I asked him regarding the saying of Allah: 'Those who invoke not with Allah any other god.'...(25.68) He said, "This Verse was revealed concerning the pagans of the pre-lslamic period."
حَدَّثَنَا آدَمُ، حَدَّثَنَا شُعْبَةُ، حَدَّثَنَا مَنْصُورٌ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، قَالَ سَأَلْتُ ابْنَ عَبَّاسٍ ـ رضى الله عنهما ـ عَنْ قَوْلِهِ تَعَالَى {فَجَزَاؤُهُ جَهَنَّمُ} قَالَ لاَ تَوْبَةَ لَهُ. وَعَنْ قَوْلِهِ جَلَّ ذِكْرُهُ {لاَ يَدْعُونَ مَعَ اللَّهِ إِلَهًا آخَرَ} قَالَ كَانَتْ هَذِهِ فِي الْجَاهِلِيَّةِ.
